what is the absolute easiest way to make 450rwhp w/o spraying?
I have a bet going on with my brother that I can make 450rwhp by the end of this year. Just got the car to run so now I'm starting to build. Right now it's all stock besides block hugger headers and an intake (vortec elbow w/filter). I can pretty much go two routes, forced induction or stroker.
If I go forced I would probably go 8psi. Along with that I would get a cam, injectors, head porting, head porting for lower compression. Can I get 450rwhp with this setup? I would spend about $5000
If I go stroker I have some parts in my garage which consist of Eagle 3.875 crank, Eagle 6" H rods, SRP pistons, block bored .030" over w/ 4bolt splayed main caps, set of AFR stainless 2.08/1.60 valves, solid roller cam. I know I can get 450rwhp with this but just going to cost another $4500+ after I add up the AFR heads, head work, valvetrain, and having someone put it together.
Do you guys have any thoughts on this ? I might be leaving a big factor out here I don't see. I'm leaning moreon forced induction cause I know I want over 800hp someday going single T88 turbo and the stroker will be a high compression engine so I won't be able to use it.
BTW, is there any way possible I can get 450 with stock block staying NA? Sorry if I sound like a total newbie. My first V8 and don't know what it's capable of yet

Yeah it would be possible to get to 450rwhp with the stock block as a 350. You would need some good afr heads, a really good size cam(maybe a custom cam would be best in this situation), and all the other goodies that you would need in any situation. But i think you would be just better off going forced induction, or the 383 stoker. It would just be easier to get the kind of power your looking for. You could even do a FI 383 Stroker.
With the parts you already have i would just do the stroker. If you went with the FI you would still have to beef up your internals to make the kind of power you want. IMO i would just do the stroker with lower compression to accomidate your turbo when you have a chance to get that worked out.

A 3.875 stroke with .030 overbore is going to be a 396. Also you stated that you have 6" rods, I hope that means your pistons are custom SRPs because the only off the shelf pistons that work with a 396 need a 5.85" rod.
But on with the question at hand....450rwhp is pushing it on stock cubes, that would require some killer heads and a custom grind cam, and then you still might not make it. Forced induction would be a good way to get there, but dont do it unless you have the money in your hand for the rebuild, because high compression + stock hypers + boost dosen't lead to good things. If it were me going for that power, I would do the stroker, because then you can reach your goal more easily because of the extra cubes.

450rwhp on the stock cubes is something that is pretty hard to do. The 8psi blown setup would sure do. If you spent the money for the heads on forged pistons and rods it may be easier because you could run up to around 10 psi. That would put you to 450rwhp for sure. Provided that you have a blower cam and good fuel system. Good luck which ever way to take

so what will make the stock pistons go when supercharging? Is it the force, heat? I can lower temps by an intercooler and water injection. Force can be minimized by lowering compression with porting/polishing of heads
It can be done but it would be alot easier with Nitrous. I made 425rwhp and 500ftlbs with a Hotcam and near stock heads last year on a 125shot. I still have the same engine with a different cam and I spray 150-175 and I bet I am pushing 500rwhp. I will dyno in the next month or so. The problem with FI and stock shortblock is the high compression and the hyperutectic pistons can't stand any detonation. Now if you change to a lower compression forged piston then could put 15-20psi of boost and make 500-600rwhp. JMO Later Clint
definitely go the stroker route if you want a solid 450rwhp.Chris

If you get a good H/C combo, and bolt ons and you are there, Maybe even more.
I disagree as well, not many people get above 400 even w/ a good H/C setup. You have to think of all of the possible combination problems and avoid them to have any hope for even 420rwhp/tq. I personally have not even seen an LS1 w/ H/C over 450rwhp more than once, and it was straight LT headers and some other goodies as well.
